brittle, coarsely granular outside, smooth within (pi. 17, fig. 3, P. 

 cunning hami). 



Distribution, Queensland and New South Wales, Australia. P. 

 cunninghami has been found living " under heaps of stones and 

 drifts of dead leaves, or buried in clusters of from 3 to 6 in the soil^ 

 The sharp edges of broken shells are used by the aborigines of 

 Port Curtis to polish their spears, boomerangs and waddies." 



The more conspicuous characters of this type are its broadly um- 

 bilicated, quoit-like shell, the presence of an appendicula on the 

 vagina, and the unicuspid marginal teeth. Both shell and dentition 

 resemble the South American genus Macrocyclis. Two specific forms 

 have generally been recognized: a large solid Queensland form, 

 cunninghami, and a smaller, thinner, keeled form of New South 

 Wales, muhlfeldtiana ; but Hedley finds that they intergrade. This 

 difference from north to south is exactly paralleled in other Australian 

 Helices. Compare Thersites richmondiana of Queensland with T. 

 novcehollandice of New South Wales ; the solid, highly colored 

 Sphserospiras, with the thinner, keeled Badistes, etc. It is a well 

 established rule that as we pass southward from subtropical Queens- 

 land to the temperate southern regions of Australia, the shells 

 become thinner, smaller, less richly dyed, and often develop a more 

 or less obvious peripheral keel. 



While the systematic position of this genus in the series cannot 

 be regarded as unquestionable, I agree with Hedley that it is prob- 

 ably to be regarded as a depressed manifestation of Panda. It does 

 not agree with that genus in that Pedinogyra has the ovo testis im- 

 bedded in the digestive gland. In Pandait is not so imbedded, but 

 is free as in the Bulimi.
